3 Claims.

The invention relates to Jordan engines and provides a plug sleeve which may be applied and removed in a simple and facile way.

Heretofore, it has been more or less conventional practice to provide a solid cast plug body which, following wear, had to be entirely removed from the shaft and replaced. This is distinctly disadvantageous and costly from the standpoint of material, time and other expense,

including the loss entailed during the idle period of the engine.

The object of the invention is to provide a plug embodying a core and a sleeve in interfitting and interlocking relation so as to admit of simple and comparatively inexpensive removal of the sleeve when necessary for repair or replacement.

The nature, characteristic features and scope of the invention more readily will be understood from the following description taken in connection with the accompanying drawings, forming a part hereof, wherein:

Figure 1 is an end View.

Fig. 2 is a section on line 2-2 of Fig. 1.

Fig. 3 is a section on line 3-3 of Fig. 1.

Fig. 4 is a section on line 4- 4 of Fig. 1.

In the drawings, the plug is shown as comprising a core I, more or less permanently fitted to the shaft 2. The sections 3 and 4 are ma.- chined to provide tapered surfaces 5 and 6 to seat a sleeve 1 which has correspondingly machined tapered surfaces 8 and 9. q

The larger end of the core is formed with channels H3, which are inwardly offset from the surface of the core, which channels increase in depth and width from the smaller to the larger end of the core. Lugs H are arranged at the larger end of the sleeve, the conical formation of the core and the depth of the channels permitting the lugs I I to pass axially of the core on the 40 application of the sleeve. The ends of the channels ill at the larger end of the core are laterally enlarged, as at l2, Fig. 4, providing abrupt shoulders l3 to limit movement of the lugs ll of the sleeve in the operative direction of the plug.

In the application of the sleeve, it is passed over the end of the core, the lugs ll passing lengthwise of the channels Ill. The movement is continued until the tapered surfaces 5 and 8 and 6 and 9 are interfltted, at which time the lugs ll of the sleeve will be slightly beyond the ends of the channels. The sleeve is then given a slight rotative movement to cause the lugs to ride befaces of the core. Thus, the sleeve is securely locked on the core, and for all practical purposes is substantially a unit therewith. When it becomes necessary to remove the sleeve for repair or replacement, the release of the cap screws and the subsequent turning of the sleeve to align the lugs II with the channels [0, will free the sleeve for simple withdrawal from the core.

Thus, the matter of repair or replacement is simple and comparatively inexpensive; no large tools ordinarily required are necessary; and the replacement can be readily carried out in the immediate vicinity of the engine, as distinguished from the usual requirement of shipping the plug to a properly equipped shop for disassembling and remounting.

Having described the invention, what is claimed is:-

1. A plug for Jordan engines comprising a core formed with a longitudinally ranging channel, a core-fitting sleeve having a lug movable longitudinally of the channel in the application of the sleeve, one end of the channel presenting an abutment in the path of the sleeve lug following application of the sleeve and rotation thereof.

2. A plug for Jordan engines comprising a core formed with a longitudinally ranging channel, the end of the channel adjacent the larger end of the core being laterally enlarged to. provide an abutment wall and a shoulder, and a sleeve fitted over the core and having a lug to ride in said channel during application of the sleeve, the

sleeve on rotation moving the lug in advance of the abutment and against said shoulder.

3. A plug for Jordan engines comprising a core having machined tapered'surfaces, the core being formed with a longitudinally ranging channel laterally enlarged at one end to provide an abutment wall and a shoulder, a sleeve fitting over the core and having corresponding machined surfaces to cooperate with those of the core, said sleeve having a lug to move in said channel during application of the sleeve and to be turned in front of said wall and against said shoulder to anchor the sleeve.
